That is usually only the case if somebody set the Quality setting to 100 in Timeline Options. Anything above 90 for SWF/JPG compression usually results in a significantly larger file with entirely no visual difference. Even the difference between 75 (the default) and 90 is so tiny it is almost unnoticeable, except for the greatly reduced file size.
